 How to obtain material via the national network

British Library Document Supply services

The British Library welcomes requests from any organisation. To order documents, you need to be a registered as a customer. Once you have registered, you will be sent full details of how to make best use of the service. To register your organisation use the link on the right.

Regional Library Systems

The Regional Library Systems are all constituted along similar lines, although membership subscriptions, and the range of services offered, vary considerably. We suggest that you visit the area's website, or contact the regional headquarters, to obtain current details.

The regional systems maintain union catalogues of the holdings of their member libraries, some being more comprehensive than others. In many cases they include the holdings of monographs, periodicals, newspapers, music, playsets, audio-visual works, etc. The Regional Library Systems also aim to facilitate the development of library services through cooperation. They work to improve the availability of resources within their areas, not just to exploit them.

 How to process payments through the British Library

Notes for suppliers and requesters

The British Library will process payments for third party interlending. The contract, however, remains between supplier and requester, and prices must be agreed between the parties; the British Library is only processing the payment on instruction from the supplier. The British Library charges a small administration fee to cover the costs of providing this service.

Ordering from location libraries

After agreeing or finding out the supplying library's charges (see Supply and charging policies), you can send your request to them by fax or email. You must quote your Customer Code and allocate a request reference number on each item you are requesting. At this stage you are giving a mandate to the supplier to instruct the British Library to debit your account with the agreed charge if the item is supplied. The supplying library then sends a claim to the British Library for any items they have supplied, listing charges, the requesting library's Customer Code and request reference number (please see section How to claim from the British Library for more details). We will then credit the supplier the total amount of the claim and debit individual requesting libraries accordingly. Requesters should keep a record of the reference number of supplied items so they can match them to the charges when they appear on their usage statement. We will add a small administration fee to each item charged to cover the cost of the service.

 How to claim from the British Library

Supplying libraries should send their claims to the British Library at least once a month; requesting libraries will expect charges to be made promptly to their account.

Your claim must quote your own Customer Code and provide the following information for each satisfied request for which you are making a claim:

  • requester's Customer Code
  • request reference number given by requester
  • whether the item was supplied as a loan or photocopy
  • price, excluding VAT

So that we can process claims as efficiently as possible, we strongly recommend you provide a listing of all items supplied each week, rather than individual returns/forms for each item supplied. We reserve the right to return incomplete or incorrect claims.

We will credit your account with the total value of the claim, including VAT for photocopy supplies. If you quote a claim reference number for each claim, we will quote this on your monthly credit statement. If you are a regular net lender, i.e. your supplies to other libraries are regularly more than your use of the British Library, we can arrange for payments to be made to you in the form of a Bank Transfer (please clearly mark your claim).

British Library template for claims

An online claim form is available to help you send your claim. Claims made via the online form will usually be credited to your British Library account within 3 working days. Payments made by Bank transfer will take between 1 and 2 weeks.
